The big thing with protein is that you do want to vary your sources. I usually try to divide it between the soy milk, soy protein/ wheat gluten protein in things like fake lunchmeat, tofu, beans (I love my vegetarian chili!), varied grains (rice, wheat, oat, etc.), peanut butter, nuts in trail mix bars (i pick kinds that have decent amounts of protein), and so forth. I usually add some soy flour to most of my baking. Every little bit helps. If you're not sure you're getting enough protein, or varied protein (soy, after all doesn't have ALL the amino acids you need), take a look at what you typically eat in a day and break down the number of grams of protein you're getting, and from what sources.
