It should be as simple as:

(add-hook 'c-mode-hook
          (lambda ()
            (add-hook 'local-write-file-hooks
                      (lambda ()
                        (shell-command "etags (your arguments here)")
                        ;; Return nil to ensure that file gets written:
                        nil))))
