Pickle the veggies: Mix vinegar, sugar, and salt. Add carrots and daikon. Let sit for 30 minutes.
Marinate the tofu: Mix soy sauce, sesame oil, maple syrup, garlic, and ginger. Add tofu slices. Let marinate for 15–20 minutes.
Cook the tofu: Pan-fry tofu in a little oil until golden and crispy on both sides (about 3–4 minutes per side).
Toast the baguettes: Slice them open (not all the way through) and toast lightly until warm and crispy.
Assemble the sandwiches: Spread mayo inside each baguette. Add tofu, pickled veggies, cucumber slices, cilantro, and chili.
