“James Bond of Vampires” is the sobriquet that Lestat gives to himself at the beginning of The Tale of the Body Thief (1992). This is likely in reference to the multiple aliases, the high security, the globe-trotting, the limitless wealth, and even the romances constantly pervading the lifestyle of the vampire Lestat.
For more perspectives on this sobriquet in the Vampire Chronicles, read the Alphabettery entries David Talbot, Lestat de Lioncourt, and Raglan James.
