Here is the format I have been using, based on what I have seen at Evidence Explained (from https://www.wikitree.com/wiki/DeVito-37):

Name the source, name the record, provide a map to finding the record, URL, date retrieved. I just copy & paste the url of the record and copy and paste the "breadcrumbs" listed above the images.

FamilySearch has started showing some Antenati results in their searches, with external links (IIRC the link wasn't directly to the record in question, just the main site). I can't find an example of their citation format at the moment, though.
