I think tempeh is an acquired taste but I actually quite like it. It actually isn't a processed product, it is a fermented product which may include soy, grains, flax, etc. I've never made it myself but I know many who have. I love tofu but I rarely make it at home, I usually have it when we go out to eat
Personally, I have no issue with faux meat (including those made with soy) but they are more of rarity for me and my husband. Today we are grilling veggie burgers which I bought from the store. I've also made veggie burgers many many times but I don't see an issue with store bought faux meat. Seitan is high protein and you can make it yourself very easily. Most people make it from vital wheat gluten, but you can even make it from wheat flour if you are inclined.
There are lots of cuisines around the world that you can base your meals on. Other cultures have much more experience with vegetarian/near vegetarian meals than us and they are good guidelines. Whether you like Asian, Indian, Ethiopian, Middle Eastern, Mexican, South American, etc - there are a lot of options. I'd recommend looking at your local library for any vegetarian/vegan cookbooks. The other option is to look at blogs.
Here are a few that are reliable in terms of quality of recipes:

And I'll say again, protein really shouldn't be an issue if you are eating balanced meals. I know a lot of vegans who are into weight lifting and what not (vegans eat no meat including fish, no eggs, no dairy) and they have no problem building and maintaining muscle.
