Narrative:

Aircraft X was executing practice IFR approaches. The first approach was ILS 32R [and] the second was gls 14L. I issued climbout instructions: 'on departure; you are cleared to ZZZ via radar vectors; turn right heading 360; climb and maintain four thousand.' the pilot read this back correctly. Once airborne again; the pilot checked in with the correct heading and his current altitude; both of which were correct. I was working controller in charge as well so I was paying more attention to tower than I should have; and I missed the part where he said he was climbing to three thousand; so I vectored him for another approach as normal. I didn't catch his altitude until after I had issued the base turn; when the aircraft was already inside the 4;000 ft. MVA.pay attention to the aircraft I am working during initial call up; then go back and catch back up with the traffic on other positions if necessary. Also check for climb when aircraft are approaching higher mvas rather than trusting [that] the pilot will do as instructed.

Title: Tower Local Controller also working as CIC reported being distracted by CIC duties and not noticing an aircraft report a climb to the wrong altitude that resulted in the aircraft flying below the Minimum Vectoring Altitude.
