Stupid question maybe: So I am on chapter 3 of Genki and learned about verb conjugations a bit. Also watched Tokini Andy on the topic. Should I be practicing conjugating Wanikani verbs as I learn them? What do you guys do? I just want to be able to read Japanese for my goal. Not sure in general how conjugation really comes into play other than reading the chapter? I need advice.
I always write the vocabulary words when I am learning them because it helps me remember them better. It is definitely one way to integrate the two, especially as you will be learning many more tenses as you progress! Good luck!
Conjugation is a topic that takes some time getting used to. It is good to do some conjugations for a few different verbs while studying the corresponding chapter in Genki as practice.
From my personal experience I would say maybe do it for around one week for the verbs that you come across. Look up what type of verb it is and try to conjugate it, look at the tables etc.
After that, for REALLY learning the topic, the best way I know of is consuming lots and lots of Japanese material. It will just start to “feel right” without having to think about all those tables and types of verbs.
Satori Reader, the Genki reading material (end of book), Comprehensible Japanese, Tadoku readers are all good material to consume to get used to verb conjugations!
All in all I would say be cognizant of the topic, look out for verb endings in reading + listening, but don’t stress too much about it and try to get perfect by memorizing tables or doing drills all the time. It will sort itself out over time.
EDIT: good luck when you get to られる、させる、and させられる later on 
Sometimes it can be useful to learn a verb either as it’s negative form or it’s て form as a way to tell apart ichidan (る-verbs) from godan (う-verbs) that just happen to end in る.
Like if you learn 食べない and 帰らない it’ll help you remember that 食べる is a ichidan verb while 帰る is a godan verb.
This technique doesn’t work for everyone, and apart from that it’s better to learn the pattern/rule behind verb forms rather than try to learn it by memorising it for every verb I think.
EDIT: That said, the same technique works with polite forms too, 食べません and 帰りません both remind you whether the る is part of conjugating the verb
Sounds like a good idea, but isn’t Genki Ch3 a little early to be talking about て- and ない-forms? XD
If you want to practice verb conjugations, here’s a tool I used to use:
i’d just do the exercises in the back/workbook
or if you want a quick quiz, you can use this, it’s pretty good to just do 5 mins if you’re waiting around instead of doomscrolling
it’s better to learn the rules for godan/ichidan verbs than specifically the conjugations for each word you learn
it’s one of the biggest grammar things in Japanese so you’re gonna get exposed to it ALL the time, so I wouldn’t fret it too much
I forgot Genki goes keigo first when teaching conjugations, but it’s only because of that that ない forms are later (Vません is in chapter 3). But the Tokini Andy video referenced (if I found the right one) does, so I don’t think it’s super advanced stuff.
Definitely not a stupid question. Bunpro has a Kaijugation game to test conjugation, I’ve found it pretty helpful. I’m pretty sure you can use it even without a free trial/bunpro sub. In general though, I love bunpro for grammar. I was using Genki but hated doing the exercises in the textbook and workbook, so now I just use Genki only for the textbook, and bunpro for recall. You can use a Genki deck on bunpro so it teaches you grammar in the order of the Genki books.
Can confirm, is available without subscription. Just checked… with all these games people are linking I’m loosing like 20 minutes of actual productive time just because I get stuck playing for a little while.
I can’t help myself, send help 
I feel it depends on your reading practice style.
If you’re going the “progressive difficulty graded reader” route then practicing simple forms early is absolutely worth it.
If you’re trying to read something not learner oriented the benefit of knowing 4 or 5 forms in the 20+ that you encounter between verbs, adjectives etc is just not worth the investment early (in my experience, your mileage may vary). Being able to parse more of the vocab / kanji or identify the most common clauses transitions, conjunctions, adverbs etc to just get the gist of the sentence by identifying more “building blocks” reduce more unknowns and help not being totally lost.
There is a critical mass of conjugation knowledge and practice for it to matter when reading.
