HMH sells a great kit with plastic tubes ready to go. You can flare the ends with a lighter to act as a flange for thread as well as ease the tippet into the opening; I only flare the front end and use a short length of surgical tubing to hold the eye of the hook on the back end. If the fly is tied in the round you don't really need to fix the hook position, so skip the surge tube, but doing so helps the fly ride the way you want with the hook down for upright winged flies. Some use a little bead to keep the eye and tube apart and moving freely.
The larger globug style hooks make good tube hooks, but I hate going up to the counter with them and getting asked "so, you tying GLOBUGS?". I just sigh and reply "I don't do globugs".
