Facebook Tag for adding connect button to other areas?

Hello,
I was curious what the actually facebook php tag was (or shortcode) to add the facebook connect button to other pages on my site. In my theme, when a user clicks login they get a popup login form but no facebook connect unless directed to the /wp-login.php form.

Example: http://stangnation.com/

At any rate, I was told by my theme designer that if I know my php tag to add I can insert it into my login form. I just didn't know what that was for this mod.

Thanks folks!
