  You aren't doing anything "wrong". 8x12 matches the proportions of the 35mm film frame. It's exactly double the size of the standard 4x6 print. The 8x10 standard matches the proportions of some medium and large format films. If you enlarge 35mm to 8x10, then 2 inches of the image get cropped out. Simply trim the top and/or bottom of the 8x12 to fit your 8x10 frame. Otherwise you'll need to give the lab very specific cropping instructions if you want them to print on 8x10.

  An additional thought . . .

I've run into this problem occasionally with my 35mm gear by framing the image in the viewfinder too tightly and being forced into an 8x12 for the print to contain everything it needs to.

If you plan to to make 8x10 portrait prints from 35mm, remember what Jon mentions about the aspect ratio of 35mm film dimensions compared to the aspect ratio of the print dimension when shooting the photograph . . . that 2 inches will have to get cut off from the long dimension. Compose in the viewfinder so that you have enough extra along the long dimension to crop for the print.

If you cannot crop it to 8x10, an alternative is to use an 11x14 or 12x16 frame and have mats made with 8x12 openings in them. 12x16 is a common frame size for other artwork. Large craft stores often have a framing area that can make these for you if they don't stock mats with 8x12 openings. The cost of a mat cut from 100% acid-free rag isn't that high.

BTW, framed prints should be spaced away from the glass slightly. This is one of the reasons for using a mat. The print emulsion can stick to the glass if it's right up against it for a long time, especially in regions with high humidity. If the frame is the same as the print size, then a hidden spacer can be used around the inside edge of the frame. The spacer is much like a very, very narrow mat that fits inside the lip of the frame.
