Since Prometheus sided with Zeus in the war between the Titans and the Olympians, he had to fight against Cronus. That is what made them enemies.
The chronology of the Greek myth is often contradictory. But Prometheus and Zeus never got along, so one might assume that the actions of Prometheus were after Zeus had overthrown Cronus.
Prometheus means "forethought", so you might say he is the god of that, but he is not an Olympian god (he was born to titans Iapetus and Themis, not Titans Cronus and Rhea) and therefore has no set domain.
The Titans were the 6 elder gods - Cronus, Coeus, Crius, Iapetus, Hyperion and Oceanus. The Titanides (female Titans) were Rhea, Theia, Tethys, Themis, Phoebe and Mnemosyne. Many of their children also received the appellation 'Titan', including Prometheus. Prometheus was known as the Titan god of forethought and it was he who was entrusted with the task of moulding mankind out of clay.
Zeus really was all about having power over the humans. He saw himself as almighty and thought nothing of the mortals. On the other hand Prometheus was willing to give himself for the humans. He was thought to bring fire to the earth from Mt. Olympus. Also he scalped humans out of clay and they were unhappy so he decided to give them fire to brighten their lives (even though he suffered harsh punishments from Zeus for stealing the flame). Of course all of this is in Greek Mythology.
Prometheus was a titan who took Zeus's (Jupiter) side when he overthrew his father, the titan king Kronos (Cronus). When the Olympians took over, Prometheus was therefore favored by Zeus and not punished as the others were. When Prometheus discovered that Zeus was hording fire away from mankind so that they would be blind to worship the gods (Zeus was afraid they would grow too independent), he stole the fire and gave it to the mortals and was named Protector of Mankind, Bringer of Fire. But, Zeus was angered when he looked down at the fires of mankind and had Prometheus chained to a rock on the Caucasus Mountains with celestial bindings. To make the sufferings worse, Zeus's sacred animal, an eagle, swooped down every night to tear out his liver. Being immortal, it always grew back. Prometheus was later freed by the hero Hercules (Herakles) as one of his 12 labors.

Poseidon's greatest enemy was his father, Cronus.
Because Cronus is a Titan, which are enemies with the Greek Gods (which includes Poseidon, Zeus, Hades, etc...), Cronus was naturally an enemy with Poseidon due to their sort of never-ending war.
