As a US permanent resident, you can start the process by filing the I-130, relative petition. This does not give her any protected status, but does give her a priority date. As soon as you naturalize, she can then file the I-485, application for adjustment of status and the accompanying forms, with a request on your cover letter to "upgrade: the petition as she is now an "immediate relative". Be sure to include a copy of your naturalization certificate with the upgrade.
