In a large mixing bowl, dissolve yeast in water. Stir in the sugar, butter, parsley, basil, oregano, thyme, garlic powder and 1 cup flour. Beat until smooth. Stir in enough remaining flour to form a soft dough. Turn onto a lightly floured surface; knead until smooth and elastic, about 5-6 minutes. Place in a large bowl coated with cooking spray, turning once to coat top. Cover and let rise in a warm place until doubled, about 1 hour.
Punch dough down; turn onto a lightly floured surface. Shape into loaf. Place in a 9-in. x 5-in. x 3-in. loaf pan coated with cooking spray.
