We know that the series shares a lot of continuity with the old, the Doctor, Tardis, Daleks, Cybermen, Master, Davros, Macra, Autons/Nestenes, Sarah Jane, K-9 etc. Plus there's the ocassional nod to past Doctors (Time Crash, Human Nature, the Next Doctor) However, there are a few smaller nods that might fly over the heads of newer fans, but are kind of cool for those who enjoy both series, or even the expanded novels/audios.
Some examples:
Kronkburgers-mentioned in passing in "The Long Game", the Kronkburgers are from DWM's very first Doctor Who comic series, the Iron Legion.
Jaime-The Doctor uses the alias Jaime McCrimmon, a reference to the Second Doctor companion played by Frazier Hines, in "Tooth and Claw".
Demons-The Doctor references the Draconians, Daemons, and the Kaleds (the humanoid species who evolved into the Daleks). Also, the Beast is voiced by Gabrielf Woolf, who did the voice of Sutekh in Pyramid of Mars. Interestingly, Satan was one of the names of Sutekh according to the Doctor.
The Ood-The Ood are said, and intended to be, genetic cousins to the Sensorites from way back in the Hartnell era.
The Key to Time-A reference in Sarah Jane, of course.
The Master-Several here, apart from the character himself. The most obvious being the use of Delgado and Ainley's voices, but also the Master's mistaking a TV show for a look at an alien race (Clangers/Teletubbies) from The Sea Devils, a reference to the Axons (Claws of Axos) and the Sea Devils again. Also, the X-ray Master in "End of Time" is very much a visual reference to the Peter Pratt/Geoffrey Beevers decaying incarnation (The whole skull with eyes bit, mainly).
This one is iffy, but in Torchwood Captain Jack refers to fairies as a "Kind of Mara". The Mara in the original series was a snake-like monster that tended to mentally possess Tegan a few times.
