Modifying Register and Login Links for WP-Admin Bar

My theme has a nice light box login, but I want to use and keep the WP-Admin Bar on the top of the site for BuddyPress users. Can someone tell me how I can do the following without using a plugin. I am using Nginx, so no htaccess file.

I made a plugin where I paste snippets and mods, is there a functions snippet that will tweak WP Admin bar to do the following:

I want the WP-Admin Bar Login Link to point to:

<a data-reveal-id="tmpl_reg_login_container" href="javascript:void(0);" onclick="tmpl_login_frm();">Login</a>

and the register link to point to:

<a data-reveal-id="tmpl_reg_login_container" href="javascript:void(0);" onclick="tmpl_registretion_frm();">Register</a>
