Combine the first 4 ingredients in a small bowl. Brush the barbecue sauce mixture over both sides of the tofu. Broil the tofu for 4 minutes on each side or until the tofu is bubbly.
Heat olive oil in a medium saucepan over medium-high heat. Add chopped onion, ground turmeric, minced garlic, and jalapeño, and sauté 1 minute. Add water and rice; bring to a boil. Cover, reduce heat, and simmer 30 minutes or until rice is tender.
Place 1 lettuce leaf on each tortilla. Divide the broiled tofu slices evenly among the tortillas. Top each with 3/4 cup rice mixture, 1/4 cup shredded cheese, 2 tablespoons yogurt, and 2 tomato slices, and roll up. Cut each tortilla diagonally in half.
