Nonfat dry milk contains over 5-6 times as much lactose as whey protein powder. This will give a sweeter flavor to food. Also, the protein found in nonfat dry milk is only 20% whey protein. The other 80% protein is made up of casein, and will give a much different texture if the food is acidic.
Baking powder is a good alternative to baking soda. Yeast isn't recommended. You really can't subsitute it. After researching on the internet I have found that this is true, baking powder would be the only substitue.
I'm not positive. The reverse substitution is for 1 tsp. of baking powder, you use 1/4-1/2 tsp. of baking soda and 1/2 tsp. cream of tartar. So you could try using baking powder instead of cream of tartar, but it's not guaranteed. If there is supposed to be baking soda and cream of tartar in the recipe and you substituted baking powder, that would be more likely to succeed.
