1. Mix the yeast, vegan sugar, and 1/3 cup warm water in a bowl; set aside. Mix the flours and salt in a bowl, and add the yeast mix.
2. Add 1 cup water. Mix the dough until smooth, about 5 minutes. Let rise, covered with a damp cloth for 1 hour. Punch down, and divide into two or four loaves, then slice tops about 2" across, 1/4" deep.
3. Sprinkle corn meal on bottom of baking sheet, so bread won't stick. Place in cold oven set to 350 degrees F. Bake for 1 hour. For crustier bread, place a pan of water on the bottom of the oven for first 30 minutes, then remove.'
