Cut tofu in half crosswise; reserve one tofu half for another use. Cut tofu half lengthwise into 3 (3/4-inch-thick) slices; cut each slice in half diagonally. Arrange tofu pieces in a single layer on several layers of heavy-duty paper towels. Cover tofu with additional paper towels; place a cutting board on top of tofu, and let stand 15 minutes.
Combine orange juice, 1 1/2 teaspoons soy sauce, rice vinegar, honey, 1/4 teaspoon chili garlic sauce, and ginger in a shallow dish, stirring with a whisk. Remove cutting board and paper towels from tofu; sprinkle 1/8 teaspoon salt over tofu. Add the tofu slices to the orange juice mixture in dish, turning to coat. Cover and marinate at room temperature 30 minutes, turning tofu slices after 15 minutes.
Heat a grill pan over medium heat. Coat pan with cooking spray. Drain tofu; discard marinade. Add tofu to pan; cook 3 minutes or until lightly browned. Turn tofu over; cook 2 minutes. Set aside; keep warm.
