Put cheeses in large bowl and let stand at room temperature approximately 30 minutes to soften. Add garlic salt, onion powder, curry powder and liqueur and mix until very well blended. Cover lightly and put in refrigerator to set, approximately 30 minutes.
Spread chopped pecans on a large piece of wax paper. Separate cheese into two 5 to 6 inch balls or 1 large ball. Place cheese mixture on nuts, roll gently to cover and shape. Put on serving dish. Garnish with pecan halves around edge. If desired, drizzle 1 Tbsp praline liqueur over top for additional flavor.
Chill to set again. Serve at room temperature with choice of crackers.
