Is there a bread that does not contain wheat oats or soy?
Yes there is
Soy: depends on the kind. It will be clearly labeled. Wheat: it will either be clearly labeled, or in the case of oats- Oats are almost always processed with wheat. Oats also contain a very small amount of protein very similar to gluten. It would be best to avoid Quaker Oats if you cannot have gluten. There are plenty of brands out there you can have.
This is from wikipedia page on soy sauce: Most varieties of soy sauce also contain wheat. Individuals with a wheat allergy, Celiac disease, or a gluten intolerance should avoid soy sauce that is made with wheat. However, some naturally brewed soy sauces, made with wheat, may be tolerated by gluten intolerant individuals, because gluten are no longer detectable.
