Hi Alex,
Your NIE does not expire, it's your unique tax identification number and you have it for life.
The residency issue requires a little more explanation. As an EU citizen, you apply for a Certificado de Registro, rather than Residency. However, the process is exactly the same and the Spanish call it Residencia!
As you only had 'temporary' residency, i.e. less than 5 years' continuous registration, and have been out of Spain for 5 years, your residency has already expired. But did you de-register when you left Spain? If not, you may be able to resurrect it by applying for 'permanent' residency, but there's a risk attached in that the authorities could ask for proof of your Spanish income tax declarations for the last 5 years which, presumably, you haven't been submitting?
In your situation, I would simply apply for registration again - it's a relatively straightforward process for EU citizens. To maintain your residency, you should not leave Spain for 183 days (6 months + 1 day) or more in each 12 month tax year of the first 5 years. You can then apply for 'permanent' residency, following which you are allowed to leave Spain for a continuous period of up to 2 years.
If you need help, I'd recommend speaking with Uma Sanz, a gestor who works for Get Legal in Spain:
