Hi Andrew. The gram/besan/chickpea flour is fine - (all made from chickpeas,) as is the rice flour, obviously from rice!
Only caution would be the baking powder. Bicarbonate of soda and Cream of Tartar are OK (if making your own, proportions 1:2)) but check contents if you are using a commercially premade version.

Should have added that wine/cider/balsamic 'distilled' vinegars are fine but not malt vinegar.
You are also better off making your garam masala increase anything else slips in (accidentally or on purpose!) during the commercial grinding & mixing process.
