One of the following hooks will do what you want, depending on whether
you want the hook to trigger before, after, or during ERC's auxiliary
text display functions (button highlighting, timestamps, et al).

erc-insert-modify-hook
  Variable: Insertion hook for functions that will change the text's appearance.
  ...

erc-insert-post-hook
  Variable: This hook is called just after `erc-insert-modify-hook'.
  ...

erc-insert-pre-hook
  Variable: Hook called first when some text is inserted through `erc-display-line'.
  ...
