Fill one quarter of the smoker box with hickory wood chips and preheat the smoker to 225°F (107°C).
Season the chicken thighs all over with kosher salt and freshly ground black pepper.
Place the thighs directly on the top rack of the smoker and smoke until the internal temperature reaches 165°F (about 2 hours).
Remove the chicken, let rest 5 minutes, then discard the skin and pull the meat into bite-sized pieces; set aside.
While the chicken smokes, warm 1 tablespoon olive oil in a skillet over medium heat, then add the diced onion, minced garlic, minced ginger and a pinch of salt; cook, stirring occasionally, until softened, about 5 minutes.
Add the curry powder, ground cumin, and ground turmeric to the skillet and cook, stirring frequently, for 1 minute to bloom the spices.
Transfer the cooked aromatics to a blender with the white vinegar and blend until smooth.
With the blender running, stream in 2/3 cup olive oil until emulsified into a vinaigrette, then season to taste with salt.
Place the pulled chicken in a medium bowl and add several spoonfuls of the curry vinaigrette; toss to coat. The chicken should be well coated but not swimming in sauce. Adjust seasoning with salt as needed.
To serve, place a handful of salad greens on each plate, top with one quarter of the curried pulled chicken, and sprinkle with golden raisins, sliced red onion, chopped toasted cashews, and cilantro leaves.
Finish with a light drizzle of extra vinaigrette and serve remaining vinaigrette on the side.
