囃はやす
囃す is the base verb meaning to cheer or accompany with music/noise. はやし立てる adds the nuance of doing it loudly, persistently, or in a rousing manner.
冷ひやかす
冷やかす means to tease or make fun of someone, but often in a more lighthearted, bantering way, without the loud, group-oriented connotation of はやし立てる.

Compound of 囃す (はやす, 'to cheer, to play accompaniment') + 立てる (たてる, auxiliary verb meaning 'to do vigorously or repeatedly').
