Sunny set us up the bomb

First, gain enough credits that you can Vamp the corp to zero. Magnum Opus, Data Folding, Daily Casts and Underworld Contact all help do this.

Next, use Tyson Observatory to get out EMP Device and Security Nexus. Now you can Vamp without needing an icebreaker. This should give you some breathing room while you find and install your breakers.

Play Another Day and steal some agendas for even more credits. If you see an agenda on top of R&D with Globalsec Security Clearance, Councilman can prevent Jackson from shuffling the deck before you take it. If the corp is drawing a lot to get around your GSC 'lock', use Tyson to get your HQ Interface.

One possible edit is to include Same Old Thing so vamp can be repeated. Or if there's a lot of Breaking News in your meta you might consider New Angeles City Hall.
