You should add the yasnippet ac-source. I have this in my init files:
(defun add-yasnippet-ac-sources ()
(add-to-list 'ac-sources 'ac-source-yasnippet))
Then for every mode where I want the yasnippet source enabled, I add add-yasnippet-ac-sources
to that mode hook:
(add-hook 'ruby-mode-hook 'add-yasnippet-ac-sources)
