Set your Central Administration web application and site to run on SSL, along with all of your other web applications and sites in SharePoint.

Create a Cname record that resolves to your load balancer.

Create a binding in IIS for your Central Admin site on port 443 with your new binding

Change your default AAM to match the new vanity url, now verify that the registry changed, too.
