You are in luck, I just returned from a week of gluten-free vegan camping! I used a camp stove, a camp fire, and a cooler for my food storage and cooking. You don't mention if you will be using a cooler or not, but you probably should so you can keep some produce, non-dairy milk, etc. Here is a run down of the meals I had:

Breakfast:
Most days, oatmeal with mixed nuts, dried fruits, and fresh fruit mixed in. I added some soy milk to mine.

Home fries made from potatoes left in the embers of the fire over night, chopped onions and garlic, celery, spices, cooked in a pan with a little canola oil. Top with ketchup.

Johnny Cakes made from corn meal mixed with water, cooked like a pancake and topped with fresh fruit and some maple syrup

Grits made from corn meal and topped with some non-dairy "butter", as a side for the home fries. Can add lots of other things to this as well

Dinner:

Beans made from a variety of canned beans, mixed with ketchup, maple syrup, hot sauce, garlic, onions, spices, cooked in a pot. Ate these with pan fried tofu hot dogs (just found out that a lot of these are gluten free now!) on brown rice bread with relish and mustard.

Burritos on corn tortillas with a filling made from onions, peppers, beans, veggies, fried in a pan. I added some soy cheese and salsa to mine.

Corn pasta from trader joes, mixed with different canned beans for a "Pasta Fagioli" style dish.

Corn pasta from trader joes, topped with a sauce made from canned tomatoes, chopped and stir fried veggies, and soy chorizo from trader joes.

Vegetable stir fry made from chopped and fried veggies (we brought a whole bunch of zucchinis and summer squash from the garden) and tofu, over brown rice.

Lunch:

Left overs! Also, potatoes cooked in the fire embers overnight make for an easy lunch the next day, just top with whatever you have (salsa is always good!).

Snacks:

Dried fruit, dried nuts, rice cakes, peanut butter, apples, oranges, rice crackers, popcorn. Also, a huge case of woodchuck hard cider

I hope this helps! Everything I made and brought was fairly healthy and very yummy. I didn't track calories for the week, but I was doing a ton of hiking, swimming, and kayaking, so I think it all cancelled out in the end. If you are staying active, it shouldn't be a problem! I shared my meals with the rest of my family, a combo of gluten-eating vegans and vegetarians, and they either ate the same thing as me or made a simple substitute (ex- no one wanted to eat my corn pasta, so we also made a pot of regular pasta). Enjoy your camping trip!!!

I do a lot of g-f oatmeal, rice noodles with a curry sauce and veggies (coconut milk and curry paste), fish, rice, salads and fruit.

I bought a whole case of these breads and snack bars for my friend who was in Alaska in the wilderness for 3 weeks. He loved them. It is called Love Force Raw foods and they have amazing breads made from nuts and sweetened cake likes substances. The breads are great for sandwiches and are totally gluten free and all vegan. Believe it or not the plain bread is the best.
