Whisk lime juice, vegan fish sauce, brown sugar, minced garlic, and sliced chili in a small bowl to create the dressing; set aside.
Toss tempeh cubes with soy sauce and sriracha in a bowl and marinate for 10 minutes.
Prepare rice vermicelli according to package instructions, drain, and rinse under cold water to stop the cooking process.
Heat vegetable oil in a non-stick skillet over medium-high heat and fry tempeh until golden and crispy on all sides, approximately 6-8 minutes.
In a large mixing bowl, combine the chilled noodles, shredded carrots, julienned cucumber, cilantro, and mint.
Add the warm fried tempeh to the noodle mixture and pour the dressing over the ingredients.
Toss thoroughly to ensure even coating of the dressing across the salad.
Divide into bowls and garnish with crushed roasted peanuts immediately before serving.
