I love to cook Fantastic Foods over a camp stove when camping. Not sure if you will one of those in order to boil water? But I believe they are all vegan, and they make sloppy joes, taco filling and chili that are great and taste amazing when camping. They are also very light to carry, although some (chili is one) require a can of tomatoes or beans.

Other ideas:
Breakfast: Bottled smoothies, luna bars, granola, tofu scramble, peanut butter and jelly, vegan muffins or donuts (ha, not the healthiest, but yummy vegan treats!). coffee w/silk soycreamer
Lunches/dinner: hummus, veggies, fruits, tofurky sandwiches, chips w/salsa/guacamole, trail mix, veggie burgers, fantastic foods mixes, dehydrated instant soup/potato/noodle cups (the kind you add hot water to) Tokurky sausages and my favorite mock meat sausages are these soy free vegan ones:

oh and tortillas pack a bit better than bread, so it's good to do wraps. sometimes i grill portabella caps (brush with light itallian dressing) when others are doing steak, or I take a foil pack and add corn, beans and cut up potatos, add salt and a liquid (like beer, even though i don't even like beer), some onions, spices, etc and fold it all up and put it in the fire. everything will cook into a yummy veggie hash you can eat with a fork. yuuuumm. grilled corn on the cob is good too, just put it right on the grill or the fire in the husks. also, you can heat a can of baked beans near the fire, but make sure you let it cool before trying to open or it will explode everywhere!
