I know some gluten free vegans and actually a lot of commercial products that are vegan are also gluten free, much to my dismay (as I like gluten). I know a lot of the gluten free/vegan cookbooks on Amazon focus on baked goods but if you are also rice free, that'd eliminate some stuff. You might want to look into a raw 'cookbook' or website for other ideas.
How about Chia Seed pumpkin pudding, something like this: (or google for similar recipes)
A quick google came up with this quick list which reminds me, I really like sweet potatoes as a snack but you can also make baked sweet potato chips/fries
This forum might also help but most people there probably eat beans and rice. This is a vegan forums gluten-free sub forum.
People on Goneraw tend to use dehydrators which you may not have but a lot of similar items can be created in your oven, here is their recipe index
And is there a reason you are cutting out beans? I can tell you if you are cutting out meat, dairy, beans, eggs then you will probably get most guidance from the raw vegan community. I personally wouldn't do it and there are a lot of benefits to beans. I've only heard of one medical condition that recommends cutting out beans, possibly low potassium diet? Again, there are vegans that do it but I wish them lots of luck, I love my beans.
