Supplication for Breaking the Fast
ذَهَبَ الظَّمَأُ وابْتَلَّتِ الْعُرُوقُ وثَبَتَ اْلأَجْرُ إِنْ شَاءَاللهُ
dhahabadh-dhama'u wabtallatil-'uruqu wa thabatal-ajru insha allah
The thirst has gone, the veins are moistened, and the reward is confirmed, Insha Allah.

It is highly recommended for those who are fasting to increase their supplications before and after breaking the fast, because the supplication of a fasting person is one of the three supplications that are not rejected.
