Place the dry soy curls in a large bowl and cover with the warm vegetable broth; let soak for 10 minutes until fully tender.
In a small glass jar or bowl, whisk together the peanut butter, tamari, rice vinegar, maple syrup, sriracha, grated ginger, and minced garlic until the sauce is smooth and emulsified.
Drain the soy curls thoroughly, using your hands or a clean kitchen towel to squeeze out as much excess liquid as possible to ensure a better sear.
Heat the sesame oil in a large non-stick skillet over medium-high heat and add the soy curls, sautéing for 5-7 minutes until they are golden-brown and slightly crispy on the edges.
Pour the peanut sauce over the soy curls in the skillet, tossing constantly for 1-2 minutes until the sauce thickens and coats every piece beautifully.
To assemble, spoon the warm soy curls into the butter lettuce leaves and top with shredded carrots, cucumber matchsticks, sliced green onions, and fresh cilantro.
