Place all the spice ingredients in a bowl and mix together. Add the garlic paste, olive oil, worcestershire sauce, and red wine vinegar. Mix well.
Toss the marinade and the beef together in a bowl. Cover and refrigerate for at least 1 hour to a maximum of 3 hours.
Take your wooden skewers and let them sit in water for 30 minutes. This will prevent them from burning on the grill. Pierce the beef with a wooden skewer. Place 4 pieces of beef on each skewer. Preheat your grill.
Once the grill is nice and hot, oil the grate to prevent the skewers from sticking. Cook directly over the heat and turn the skewers every 3-4 minutes until each side of the skewer has a nice char.
