There are various tricks, but I don't think any of them are particularly useful. ("Think in treble clef, then transpose down a major ninth...") Tenor clef isn't any harder than treble or bass clef--just less familiar for most of us. Practice your Milde and Weissenborn etudes until tenor clef becomes automatic! (Then start relearning to play in bass clef.)

Good luck,
