What were some practices that followers of Caananite/Phoenician religion would do to worship their gods?

The Pheonecian religion was largely polytheistic. The two most important deities were Baal-hamon (god of the sky and of nature) and Melquart (patron god of Tyre). An important ritual in Pheonecian culture was the sacrifice of either and animal or a child to a certain god. These ritualistic sacrifices were key components in many iron age religions. The Romans, Greeks, Gauls, and Canaanites were known practitioners. Child sacrifices, however, are normally associated with the Canaanites and Pheonecians. The Sicilian historian Diodorus stated that they would sacrifice children by burning them alive on large bronze statues of their gods.

The accuracy of these claims is dubious though. Many believe the Romans, after the Punic Wars, exaggerated the brutality and savagery to dehumanize the enemy. Regardless, evidence from archaeological digs in Pheonecian cities show mass graves of children, showing that such sacrifices indeed occurred.

The exact practice of child sacrifice would be done by parents to gain favor with the gods. A pair of Carthaginian parents, for example, would pledge the life of an unborn child for good fortune and wealth.
