Place tofu on several layers of heavy-duty paper towels. Cover tofu with additional paper towels, and let stand 5 minutes, pressing occasionally.
Heat oils in a large nonstick skillet over medium-high heat. Add tofu; sauté 7 minutes or until browned. Place in a bowl. Drizzle with soy sauce and vinegar; toss gently to coat. Cover and chill at least 1 hour, stirring occasionally.
