'Zurückliegend' is the present participle of the verb 'zurückliegen'. This verb literally means 'to lie behind something' or, figuratively, 'to lie in the past'.

The event already took place several years ago.
The noun that 'zurückliegend' describes reveals the meaning. If it refers to time (e.g., 'Jahr' (year), 'Monat' (month)), it is about the past. If it refers to a place (e.g., 'Garten' (garden), 'Gebäude' (building)), it is about spatial position.
Das zurückliegende Jahr war für die Firma sehr erfolgreich.

In the time-related meaning, the word is often combined with nouns such as 'Woche' (week), 'Monat' (month), 'Jahr' (year), 'Zeitraum' (period), or 'Geschäftsjahr' (fiscal year).

'vergangen' and 'zurückliegend' mean almost the same thing in this context: something lies in the past. Both words are used for times, events, or experiences that have already happened. 'vergangen' is very common in everyday language, especially in expressions like 'vergangene Woche' (last week) or 'im vergangenen Jahr' (in the past year / last year). 'zurückliegend' sounds a bit more factual and fits well in reports or more precise descriptions.
