Dissolve yeast in 1/3 cup warm water in a large bowl; let stand 5 minutes. Lightly spoon flours into dry measuring cups, and level with a knife.
Add flours, wheat gluten, oil, and 1/2 teaspoon kosher salt; stir until a soft dough forms.
Turn dough out onto a lightly floured surface. Knead until smooth and elastic (about 3 minutes).
Place dough in a bowl coated with cooking spray, turning to coat top. Cover and let rise in a warm place (85), free from drafts, 1 hour or until doubled in size. (Press two fingers into dough. If indentation remains, dough has risen enough.)
Preheat oven to 45
Punch dough down.
Roll dough into a 10 x 14inch rectangle on a lightly floured surface.
Place dough on a baking sheet coated with cooking spray and sprinkled with cornmeal. Cover and let rise in a warm place (85), free from drafts, 20 minutes.
Sprinkle cheeses evenly over dough. Arrange tomato slices in a single layer over cheese.
Combine basil and remaining ingredients in a bowl; sprinkle mixture evenly over tomatoes.
Bake at 450 for 12 minutes or until crust is golden brown.
