I used paper strips and paste for the mask in this demonstration, but you can use drywall joint compound with paper maché clay, too. You can even use it with the silky smooth air dry clay if it doesn't come out quite as smooth as you want to. Any brand of drywall joint compound will work. If you use just a thin layer you can easily remove it with a damp sponge or cloth. If you put on too much, or if you're in a real hurry, you can use sandpaper - but do it outside to keep the dust out of your house, and use a mask to keep the dust out of your lungs.
