Individual packages are not signed, so you would basically need to manually repeat the process which APT uses for verifying package integrity:

• calculate package's MD5 and SHA sums
• look up the package in the Packages file, check they match, calculate the Packages(.gz) file's sums
• look that one up in a Release file
• verify Release file's signature: Release.gpg

You can find each of these files simply by browsing the archive tree.
