Combine flour and next 6 ingredients (flour through black pepper). Dredge each tofu steak in flour mixture. Dip into egg; dredge again in flour mixture. Heat 2 teaspoons oil in a large nonstick skillet over medium-high heat. Add tofu steaks; cook 6 minutes, turning after 3 minutes. Remove from skillet; cut each tofu steak into 4 wedges. Keep warm.
To prepare the ginger sauce, combine vinegar, sugar, 1/2 cup water, and soy sauce in a small saucepan; bring to a boil over medium-high heat. Reduce heat, and simmer 3 minutes or until sugar is dissolved. Combine cornstarch and 1/4 cup water; stir into sugar mixture. Bring to a boil, and cook 1 minute or until thick. Remove from heat; stir in ginger. Keep warm.
To prepare vegetable stir-fry, heat 1 teaspoon oil in skillet over medium-high heat. Add bell pepper and snow peas, and stir-fry 2 minutes. Add tomato, and stir-fry 1 minute. Serve over pasta, and top with ginger sauce and tofu wedges.
