I think the key word here is "promotion". If you are getting a promotion then I believe part of the promoting should be in the salary or package you get. Companies in general will try to get as much out of you as possible for the least amount of remuneration as possible (of course that is a mass exaggeration but I don't think it's far off the mark)

IMHO Promotion === Promotion in responsibilities + promotion in expectations === promotion in remuneration package

It can be awkward bringing this up and you shouldn't feel like that at all. However I would bring this up before excepting the role. Once you accept you are doing the work and so whatever value the company holds for that role you should be receiving in your pocket.

Perhaps send an email to the boss along the lines of.

Hi ...,

I would like to discuss further the role of team leader role within the company. Some of the topics I would like to go over include:

• What exactly does this role cover. In what capacity will my responsibilities increase.
• With this new role expectation is there any remuneration benefit to go with the extra responsibility and expectations. If not immediate will there be any review along these lines in the future.
• I really enjoyed my work, life balance in my previous role. Do you expect this to be effected by a team leader position in regards to your expectations on how it should be filled.

Thanks and I look forward to talking with you some more on this great opportunity....

Or something along these lines.
