I can tolerate gluten but it'd be nice if it were gluten free too.
Not really a bread, Matzo????
Yes, I think crackers are the way to go. Lean breads (breads without fat, dairy, or eggs) use yeast for leavening, and breads that don't use yeast use baking soda or baking powder but also usually involve eggs and/or dairy. Salt-Risen Bread doesn't use yeast (it rises thanks to a salt-tolerant bacterium present in cornmeal), but all the recipes I've seen for it use dairy.
I make this one with buttermilk, but you could certainly sub soy milk or rice milk perhaps an ounce or so less. http://thesolitarycook.wordpress.com/2013/07/16/midsummer-soup-and-bread-the-true-story/
Indian chappati is a flatbread made of flour and water, a bit of salt.

Drat. I forgot that yeast was an excluded ingredient. How about pappadoms: http://www.youtube.com...
Not sure about the yeast part, but if you want a substitute for eggs, you can make flax/chia eggs. 1/4C water + 2T flax seeds or chia seeds = 1 egg equivalent.
I recently came across this recipe that looks easy enough. It's a soda bread and looks pretty too. http://www.veganlovlie.com/2014/12/virtual-vegan-potluck-december-2014.html
There are step by step photos and a video too. I think I am going to try it.
Let me know if you do too.
