The difference between baking soda and baking powder is that baking
soda produces CO2 when it reacts with an acid while baking powder
produces CO2 when it is heated. (Baking powder is typically baking
soda plus a salt that turns into an acid when heated.)

If your dough or batter is acidic (sour) -- i.e. made with sour-dough,
yogurt, buttermilk, sour-cream, cream of tartar or similar -- you can'
use baking soda instead of baking powder. If your dough is not acidic,
you have to use baking powder or add a bit of acid (vinegar, lemon
juice) to the dough as well.

For pancakes and flat cookies made from acidic doughs and batters you
can also use salt of hartshorn (baking ammonia) or a 50/50 mix of
baking soda and salt of hartshorn.
