If you’re using the Tags special field, it should show the tags separated by spaces.
I wrote some fancy code to show the tags in colors:
Here is a demo deck with the code used: Gofile - Free file sharing and storage platform
I use similar code but as an add-on to show the tag list in all my note types without modifying the templates: anki-misc/tag_list at master · abdnh/anki-misc · GitHub
Or you can try the Clickable Tags add-on.
