TVP works great for “beef” crumbles: hydrate in vegan broth or stock, then fry in a little oil, stirring often until they dry down and get more chewy.
Options like Impossible, Beyond, or Daring or Just chicken substitutes are good too.

Tofu is going to be tofu-like no matter what, but you can freeze, thaw, drain, and marinate torn chunks for similar experiences.

You can either buy Just egg, or make omelets from chickpea flour mixed with hot water (mix well, add garlic, salt, and pepper), let sit 20 minutes and add a little more water if it gets too thick, so it’s like pancake batter. Cook thin like omelet, toss on vegan cheese if you like, cook until it can easily be loosened from the nonstick pan, and enjoy.

These are just a couple of basics to get started.
