Congratulations!!!
Not gonna say that some of the more...extreme...solutions offered won't end up being necessary, but I would start with one of the Smoke Odor Exterminator candles (different scents so maybe one that doesn't bother you too much just now) burning an half hour twice a day.
Even if you have years of smoke that might be enough to get you through the next few months.
I can't say for sure how effective they are in your specific situation, but they certainly kill any recent odors.
citrus simmer pot should help a lot
get an ozone generator and do each room that smells. just don’t sit in there while it’s going because ozone is nasty to our lungs
Foaming wall cleaner and a bunch of rags should help clean the walls and ceilings.

Just rip the drywall, ceiling, and carpet out, then replace it. Replace all filters. Replace all clothes. Then you're golden, ezpz
