Slice salmon lengthwise into 10 to 12 narrow strips. Thread each strip onto a skewer; place skewers in a shallow dish.
Whisk together soy sauce, honey, vinegar and spices.
Pour over skewers, turning to coat.
Let stand at room temperature for 30 minutes.
Drain marinade into a small saucepan; simmer over medium-low heat for several minutes.
Grill skewers over medium-high heat on a lightly oiled grill, brushing often with marinade, for 4 minutes on each side. Squeeze lemon wedges over salmon; serve warm.
