I'm not sure about static library, but you can find dynamic-link library example in FASM\EXAMPLES\DLL

this way a import section looks.
Code:
; *** Import table just follows code & data ***
dd 0,0,0,KernelName-CCBase,KernelTable-CCBase
dd 0,0,0,User32Name-CCBase,User32Table-CCBase
dd 0,0,0,0,0

KernelTable:
ExitProcess     dq _ExitProcess-CCBase
dq 0
KernelName      db 'KERNEL32.DLL'
_ExitProcess:   db 0,0,'ExitProcess',0

User32Table:
MessageBox      dq _MessageBox-CCBase
dq 0
User32Name      db 'USER32.DLL'
_MessageBox:    db 0,0,'MessageBoxA',0
    

how the export section looks like?

candyman, here is what the imports/exports looks like from one of my libraries. W8 seems to need reloc section to be readable and any windows seems to not like empty reloc section.
Code:
section '.idata' import data readable writeable

  library kernel32,'KERNEL32.DLL',\
          user32,'USER32.DLL',\
          gdi32,'GDI32.DLL',\
          gmp,'GMP.DLL'

include 'api\kernel32.inc'
include 'api\user32.inc'
include 'api\gdi32.inc'

Code:
struct  tExportDirectory
  Characteristics               dd ?
  TimeDateStamp                 dd ?
  MajorVersion                  dw ?
  MinorVersion                  dw ?
  Name                          dd ?
  Base                          dd ?
  NumberOfFunctions             dd ?
  NumberOfNames                 dd ?
  AddressOfFunctions            dd ?
  AddressOfNames                dd ?
  AddressOfNameOrdinals         dd ?
ends
