In a medium bowl, combine the softened butter, minced garlic, parsley, chives, smoked paprika, onion powder, salt, pepper, and lemon juice. Mix until well combined to create the cowboy butter.
Preheat your grill to medium-high heat.
Thread the chicken cubes onto the soaked wooden skewers, leaving a little space between each piece for even cooking.
Brush the chicken skewers generously with the cowboy butter mixture, reserving some for basting while grilling.
Place the skewers on the preheated grill and cook for about 10-12 minutes, turning occasionally and basting with the reserved cowboy butter, until the chicken is cooked through and has nice grill marks.
Remove the skewers from the grill and let them rest for a few minutes before serving.
