To get tracker to index the sshfs mount you need to tweak its settings a bit, as discussed here. (Make sure indexing external memory is on, possibly whitelist your custom directory if you don't want to use one of the defaults) However that would just add the contents to your music library.
Instead you could use xdg-open from the command line. This has the downside that xdg-open does not support multiple files as arguments and currently has limited support for different file types (see this request).
Another possibility would be to generate a m3u with the files you want. Remember to use the full path as seen on the device for this. (I don't know if playlists with files unknown to tracker work though)
In the end the easiest way to go is probably to make tracker index the directory and then create a playlist from the contents, either via media player or by hand (or with some script).
