I've given two examples here; going from concert key (like pianos and flutes) to Bb clarinet and going from Bb clarinet to concert key (which is what your question sounds like you are asking for).
*Going from CONCERT Key to Bb Clarinet.*
If the concert key is Cb major, it has 7 flats. So for the Bb clarinet transpose up one full step, taking away two flats. This will put you in the key of Db major with 5 flats.
Now lets tackle G# major. This isn't a standard key signature. The key signature used would be Ab major, which has four flats. On a Bb clarinet, go up one full step, taking away two flats. This puts you in the key of Bb.
*Going from Bb clarinet to Concert Key*
However now lets go the other way. Say the Bb clarinet key is in Cb major, which has 7 flats. Now to go to concert key one expects to go down a full step, adding two flats. Unless you are into weird notation though, you don't do it when the final number of flats would exceed 7. So now what do you do? You still go down a full step but you have to think of the equivalent note names. Cb is also B natural. So the key of Cb major is played the same as B natural, which has 5 sharps. Now you can move down a full step to A major, taking away two sharps.
Again, G# major isn't a standard key signature unless you are into wierd notations. So lets convert it to it's more "normal" rendering of Ab major, which has four flats. Now to convert to concert key, move down a full step to Gb, adding two flats for a total of six flats.
