Moving from tangible daily outputs (code etc), to longer term feedback loops can be just as rewarding, you just need to step back slightly.
Empowering others to achieve their potential, watching them grow. Watching great products evolve. Understanding and directly influencing tech decisions. Being able to look further than the next sprint. Interfacing with external parties, seeing how they approach similar / new problem spaces.
IMO, this never gets boring.
Keep a log throughout the day. It helps.
Failing that, use email, issue trackers, repos, purchase orders, inventory logs or other major communications channels / process interfaces to retroactively summarize progress. I currently do this weekly, and use it as input to reporting and planning processes.
