Sorry or do you mean, u want to transfer from 1 registrar to another registrar? If that's the case you still need that login & also go to the new registrar site & follow their instructions to transfer the domain over to them.
Once the above's sorted, you can simply find your new registrar and once you're signed up, can request the domain name be transferred.
To confirm the transfer, an e-mail will be sent to the admin contact e-mail address listed on the WHOIS record. You'll have a fixed period of several days in which to reply to this mail as directed.
Following this, you'll likely receive a similar mail from your new host which again, will need approving within a fixed number of days. These confirmation mails are a measure to protect against your domain being transferred maliciously.
That's a very rough guide and you'll find that proceedures vary slightly from one registrar to the next. Whilst I can't recommend any particular ASP hosts (although others may have suggestions), make sure you find one you're comfortable with and who are able to guide you through the transfer process if needs be.

Use the control panel of the domain registrar to update the DNS servers.
Transfer of registrar? Simple. Create an account with new registrar and ask them to arrange for the transfer of the domain. These days it's as simple as confirming an email. This assumes the email address in the WhoIs is still valid.
I've had luck with 2 different registrars in this case. I sent polite emails explaining the situation and to ask their policies. "I can prove I'm me," I said. And neither registrar asked for proof - I think I sounded so dumb they both just believed me and helped me out. :)
But what if it's not...
Different registrars have different proceedures for scenarios like this, although most are either woefully inadequate or poorly enforced.
In many cases, it's quite easy to get contact details and nameservers updated over the phone with little of no verification being done by the registrar. Proof?...what proof?...
In any case, it's important to ensure contact details - especially the e-mail address - are up to date. As the registrant of a .COM .NET .ORG .BIZ or .INFO domain, you're obliged to check your data is correct at least once a year and could - in theory - lose your domain if it isn't, although I've yet to hear of this happening. Incorrect info could also lead to renewal notices not being received and ultimately, loss of your domain - happens far too often.
