One of the most important things that upper management wants in a front-line manager is that they bring projects in on-time and on-budget. If you have any wins like that in your history, you want to try to highlight those.
If you managed a budget, that's worth highlighting.
If the projects you managed were technically complex or were complicated because of the distribution of personnel, highlight that.
If you interfaced with executive-level management, that's worth mentioning.
If you managed more than 5-6 people at a time or more than 2-3 projects at a time, discuss that.
If you had to manage conflicting personalities or manage through difficult morale issues and you did so successfully, highlight that.
If you were responsible from integrating input from people who were not developers per se (UX folks, users, etc.), discuss that.
In addition, if you want to tailor your resume for specific jobs, look at those jobs and determine what skills they are looking for and list the commonalities in your background.
