A trick that works for me (may not help if you are on time constraints) is to put something to the side briefly, pick up a video game (I find EVE gives me lots of good content to write on), and then write a quick self-view of events that went on.
Was having some of the worst writers block when, for shits-&-gigs, I decided to go on a solo flight in EVE and write it up based on encounters, places visited, and general events of the night. What started as a single boring paragraph quickly evolved through rewrite to be a short novel where the subject matter (space-ships) instead became Fantasy. Enemy ships were written out as beasts with their specific fittings described out as natural weaponry or defenses, and even events as simple as "listed out of warp scrambler range and warped off" quickly evolved into fully flushed thoughts.
"With a deafening shriek the Fly Catcher recoiled, the harpooned appendage previously embedded in my frigate's hull snapped back and flailing about. The Repair Nanites flooded to the hull breach had done their job by both severing the appendage and soldering the damage in one go. Navigation systems flickered back into life moments after and little time was wasted. The Tormentor's engine groaned & whined as I forced it back into full thrust, burning away as the beast lurched forwards again, determined not to be robbed of its meal. With a soft hum of hyper drive and a whoop of glee I watched landscape quickly turn to blurred lines, the frustrated shrieks of The Fly Catcher fading into just another howl carried along the wind in my wake."
Found going on that fun tangent helped get the creative juices and general writing flow back. Specially with re-describing inanimate chunks of metal as living, breathing, beasts of lore. Donno, may help.
