In a large bowl, whisk water, tamari, honey, rice wine vinegar, oil, garlic and red pepper flakes. Submerge tofu slices in marinade and set aside for 30 minutes and up to 24 hours. Swish occasionally.
In a small saucepan over low, heat ¾ cup rice wine vinegar, sugar and salt, stirring occasionally, until sugar dissolves. Remove from heat, and allow to cool. Once cooled, add daikon, carrot and cucumber. Refrigerate for 30 minutes to pickle the vegetables. If liquid isn’t covering vegetables, add some cold water.
Preheat oven to 375°. Line a baking sheet with parchment. Place marinated tofu strips on baking sheet; season with salt. Bake for 35–45 minutes, until golden brown, flipping halfway.
In a small bowl, combine mayonnaise, Sriracha, honey, lime zest and juice and salt; set aside. To assemble sandwiches, hollow out bottom half of baguette loaves. Spread 1 tablespoon Sriracha mayo on top and bottom halves. Divide tofu between baguettes; top with pickled vegetables, mint, cilantro and jalapeño slices. Slice baguettes in half.
