You don't need to do anything special, just build your image and look at the resulting manifest file in build/tmp/deploy/licenses/$IMAGE_NAME-$MACHINE-$DATE/license.manifest (if, of course, you didn't redefine LICENSE_DIRECTORY).

For example, if I build core-image-minimal for my own generic-amd64 MACHINE I get the result in build/tmp-musl/deploy/licenses/core-image-minimal-generic-amd64-20160818141324/license.manifest:

PACKAGE NAME: base-files
PACKAGE VERSION: 3.0.14
RECIPE NAME: base-files
LICENSE: GPLv2

PACKAGE NAME: base-passwd
PACKAGE VERSION: 3.5.29
RECIPE NAME: base-passwd
LICENSE: GPLv2+
