Tofu is pretty versatile as a meat replacement or even just a general texture thing. I like to fry small tofu cubes and use them in place of the cheese in palak paneer, or instead of chicken in something like General Tso's. It takes a bit more work since you have to press the tofu and find a good way to cook it so it doesn't turn out soggy (and it's usually more expensive), but I'm a meat eater and it's satisfying to me.

Beyond/Impossible Meat is also pretty good imo. I actually tend to like it better than real beef, but that's definitely not a majority opinion. If you like the taste, you can crumble the patties for ground beef texture or break them into chunks for more of a meatball vibe. I've even done a sort of faux bulgogi with chunks and gochujang sauce that works surprisingly well.

One more thing I think can help is to not try to replicate meat for everything. There are ways to make vegetarian/vegan food that let it stand on its own and still be satisfying (beans and chickpeas can help a ton), without it feeling like it's trying too hard to be meat. Things like cauliflower stir fried or batter fried and coated in some sort of sauce can be good just as cauliflower in sauce.

Finally, mushrooms, if you like them. Soaking dried mushrooms will get you stock that can replace chicken or beef stock for most things, and frying even the cheap baby bella mushrooms that come pre washed and sliced can give you a meaty texture in something that needs it.
