Honestly, my suggestion would be to scrap it. “GVT” and beginners" don’t belong in the same sentence. And the program you Frankensteined together is pretty far from GVT.
There are tons of programs you can use to put on muscle, and you can attack a legit GVT program a while down the road once you’ve established a better base. I’d go for any of the programs explained here. After 8-12 weeks, you can consider switching things up.
Are you vegan?
It sounds like you have a fairly high general activity level outside the gym, so I wouldn’t be overly concerned with packing on fat, but you do need to get some quality protein sources - peanut butter and gluten ain’t it. If you have to stay strict vegan, pea and rice proteins are better options. If you can go lacto-ovo vegetarian, that opens up a ton of more effective options.
Also, I have a feeling you and @ChickenLittle are in a similar boat, lifting, killing rattlesnakes on the farm, and whatnot. Take a look at her training log to also get some ideas.
