How do you theme specific fields in on a content type?
You could use field.tpl.php

If your field is called field_series then you will need to create:

/mytheme/anyfolder(optional)/field--field-series.tpl.php

If you inspect the variable $element then it will contain everything you'll need (tid, name, see drupal_get_path_alias for the link)

Don't forget to clear the cache once the new template has been created.
