In a large bowl, add 10 cups flour, 1/2 cup sugar, and salt. Mix to combine( I like using a whisk). Add in the bubbly yeast mixture, 3 cups warm water, and oil. Mix well, and let it stand for 10 minutes. Turn the dough out onto a floured surface and knead for 8-10 minutes.
Place the kneaded dough into an oiled bowl and cover with a towel. Let sit for 1 hour. Punch the dough down, cover it and let it rise for an additional hour.
Get out 4 non stick bread baking tins,( lightly grease tins with vegan butter/baking spray if they are not non stick.) Cut the dough into 4 equal pieces, shape into loaf shapes, and place into baking tins. Grease the tops of the loaves with softened vegan butter. Alternatively, you can dust the loaves lightly with flour or brush the tops with olive oil.
Cover the loaves again and let them rise for about 30 min. or until the dough rises to just above the rim of the pan.
