Update: As of December 12, 2018, AddThis has removed Google+ from our list of social sharing networks. If you would like some more information you can find it here.
Google Plus One can be styled according to their documentation –http://code.google.com/apis/+1button/ – by prepending the attributes with g:plusone, like this:
<a class=”addthis_button_google_plusone” g:plusone:size=”small”></a>
