Aircraft X was flying an RNAV approach. There was weather and lightning in the southeast. I received a call from ZZZ Tower saying that they have lost power and were on backups. The lighting did not work at the airport and they were using other phones to talk to airplanes and the reception for those phones only worked about 5 miles out from the field. I was on the line with ZZZ Tower getting information and creating a plan for other planes going into ZZZ. They needed us to call all inbounds since they weren't receiving any information with the Tower's power shut down. A couple minutes after getting off the phone with ZZZ; Aircraft X calls up and says he had a lightning strike and was going to hold over a fix on the published approach or something along those lines; which is an IF (Intermediate Fix) for the approach.He said he wanted to head back up to ZZZ. I told him that ZZZ just called me and said their power went out. At the time; I did not have the approach pulled up and didn't exactly know where the fix was and didn't recall there being a holding pattern there but when he mentioned it was on the approach I wanted to double check. At the time; I told him there was high terrain to the east of him and that he climb to 12000 feet; with no delay through 9000 feet. He was at 5000 feet which was below the MIA (Minimum IFR Altitude) for that area. After pulling up the approach; there was no holding pattern at that fix so I told him to fly the published missed approach except maintain 12000 feet. After a few minutes go by; he told me he was over the fix and was doing the missed approach; so he never did do any holding over that fix and was flying the approach path. Once he was reaching 12000 feet; he said he wanted to divert now for his company's request. I gave him instructions to proceed to [diversion airport]. After the thought; I do not believe I ever radar identified him. He was ADS-B so I was looking at him. I do believe I did get an altitude out of him before I proceeded him to ZZZ1.
Center Controller reported a B737 encountered a lightning strike and executed a missed approach which placed them below the Minimum IFR Altitude.
