In a small bowl, mix oil, salt and paprika. Brush the rough sides of the pita with the oil mixture. Cut each circle in 8 points. Put the pita points side by side, oiled side on top, on a large baking sheet. Cook in the center of a preheated oven of 350 F for about 12 minutes or until pita chips are golden and crispy. Put the pita chips on a rack and let cool. (You can prepare the pita chips in advance and put them in an hermetic container. They will be good up to 3 days at room temperature.).
