Either put this around the code in the plugin:

PHP Code:

if (in_array($vbulletin->userinfo['usergroupid'], array(x.y.z)))
{
    stuff only members of group x,y,z can see
} 


Or this around the code in the template:

<if condition="is_member_of($bbuserinfo, x, y, z)">
stuff only members of group x,y,z can see
</if>
