(Gluten-free) soy flour contains more oil, browns quicker, absorbs more moisture, and does not hold-form or raise as much as all-purpose flour. Store it refrigerated; Try a 25 degree-Farenheit lower baking-temperature; use 33% more of it; blend with other gluten-free flours or add xanthan-gum OR guar-gum OR pre-gel starch. Reference a gluten-free or soy baking cookbook for recipe tips.
