Depends how long you've got to learn it. My approach to transposition doesn't work overnight but has served me reasonably well over the years (humble apologies if this sounds like boasting! I assure you that is NOT the aim, just passing on what I've been taught and partly worked out for myself!) and that is to treat whatever your transposition as a new set of fingering/slide positions (after all, you've learned one so you have a sort of head start) Rules such as 'up a fourth', 'up a tone' etc. etc. are fine, but when you get to a quick passage of semiquavers, say, by the time you've worked out what the 'up a fourth' is, it's gone (not useful if you have to transpose at sight!)
I would also recommend this for reading bass clef, seeing as you'll have to learn a lot of notes with leger lines, particularly above the stave - so (for starters) a note on the second line up from the bottom of the stave with a flat in front of it is a concert Bb, (the equivalent to a treble clef bottom C just below the stave for euph) and therefore open fingering etc. etc.. Learn what the notes are, learn the fingering (and useful to learn how it relates to BB treble clef), that would be my humble suggestion.
For this particular issue (transposing bass clef to treble clef) as I said, it depends how long you have to learn it. If it's a quick fix, personally, I wouldn't recommend attempting it without writing it out (and then you have copyright issues to deal with, see Copyright FAQ forum, so the chances are you'd need to get permission)
Humble apologies again if I appear big headed, or indeed, to be talking complete ********! Good luck whatever!
Kind regards
