I'm vegan, and I plan to make the same kind of food I always do when I am camping.
Do you eat indian food a lot? They've got lots of vegan dishes (or dishes which can easily be adapted) with nonperishable ingredients that can be made in only one pot. (Dal especially) Perfect camping cuisine!
these recipes are all vegetarian and with videos, it's pretty easy to make most of them vegan.
I'm not a huge fan of the fake meat although adding TVP to some chilli is always good, and usually well-received by meat eaters, too.
Try out some dishes at home. Aim for stuff that is simple to prepare, and non-perishable ingredients are always easier. (Your tomato cannot get dusty if it is diced and canned).
