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))))
