Change up your routine. Try bike riding when you're not doing yoga, it's a great way to burn calories. If your body has gotten used to your routine, you need to trick it by changing your routine a little bit.

The point is just to stay hydrated, so I don't think flavoring the water with tea or anything else changes the fact that it is keeping you hydrated.

Tea is mostly water so yes. I took a nutrition class a while ago and the instructor told us milk counts as well.
